CREATION OF A STAIRWAY WITh ARRAY ANd BEvEl mOdIFIER With the default cube selected edit it in “Edit” mode using the 3D mani-pulator. We form a step.

If the center (Origin) of the object to become bad we can re-center it with the “Origin” of the toolbox in “Ob-ject” and selecting “Geometry to Origin” in the menu that appears.

Then we add a modifier “Array” in the properties panel “Modifiers”. We click Add and select the Array Modifier.

With the slider “Count” select the number of steps you want. And with sliders “Relative Offset” adjust the dis-tance between them.

To bevel the edges of the steps we can add a modifier “Bevel”.With the slider “Width” adjust the size of the bezel.

Then, with the edge selection mode enabled:

select the edges you want to apply to the bezel with “Ctrl + Right”

And if you want the bevel is applied only to certain edges can select “Weight” and “Average”, then we have to enter “Edit” mode and in the toolbox (“T”) all the way down to “Mesh Options “we have select” Tag Bevel “in the blind” Edge Tag Mode “.

CONTROl BY EmPTYWe add an empty object (Empty). Next select the ladder again and enter the name of the object in the cell empty “Object Offset”, the modifier tab “Array”. We also have to disable “Constant Offset” and “Relative Offset”.

Selecting the empty object (Empty) can con-trol the ladder through 3D manipulator.

With the 3d manipulator move mode: define the separation between steps (also can press the letter “G”).

In rotate mode: define rotation between steps. (You can also press “R” key).

In mode to Scale: define the size difference bet-ween steps. (We can also press the letter “S”)

* NOTE: To make sure that when we move the ladder does not change the transformation regarding the Empty, the Empty we become related to the ladder. For that select Empty first and then the “Shift” key down, select the ladder. Pressing “Ctrl + P” what parent it.

ThROUGh CONTROl CURvE ANd CURvE mOdIFIER We add a curve and enter the name of the cell in the “Curve” menu “Fit Type” in “Curve Fit” tab in the modifier “Array” of the ladder. We add a modifier “Curve” to the stairs and enter the name of the curve in the cell “Object”

Select the curve and into “Edit” mode (Tab.) to define it to our liking, we can even add more control points to adjust the curve better.
